10 Important Difference Between SDHC and SDXC(Tabular Form)

difference between SDHC and SDXC
What is the difference between SDHC and SDXC? 

The SD Association has released the SDHC( Secure Digital High Capacity ) and SDXC ( Secure Digital eXtended Capacity ) variations of the SD (Secure Digital) format in that sequence.

The file system used to store data indicated by the card type determines the memory card‘s capacity.

Until far, SDHC cards had had capacities ranging from 4GB to 32GB. To be more specific, the SDHC card comes in capacities of 4GB, 8GB, 16GB, and 32GB.

The SDXC card has a maximum capacity of 2TB. We’ll go through the differences between SDHC and SDXC cards in this article.

What Is SDHC?

SDHC (Secure Digital High Capacity) is an SD (Secure Digital) card extension that enhances the storage capacity of memory cards to 32 GB. It’s also known as the regular SD card’s version 2.0.

SDHC cards are NOT backwards compatible with host devices that only accept SD (128MB – 2GB) cards due to the fact that SDHC cards are pre-formatted with the FAT32 file system, whereas SD cards are commonly configured with FAT12, FAT16, or FAT16B.

SDHC compatibility should be included into most readers and host devices developed after 2008.

What Is SDXC?

SDXC (Secure Digital eXtended Capacity) is an SD (Secure Digital) card extension that enhances the storage capacity of memory cards from 64GB to 2TB.

It’s also known as the regular SD card’s version 3.0. They are incompatible with devices that only accept SD cards or those that only support SDHC cards.

SDXC cards are, nevertheless, compatible with the majority of devices manufactured after 2010.

This memory card is most commonly found in cameras that take RAW photos and record in 4K.

Conclusion

The SDXC standard is a more recent addition to the SD standards with storage of 64 GB to 2TB compared to 4GB to 32GB of SDHC.

SDHC and SDXC cards are huge-capacity flash memory cards based on the SDA that can be found in a variety of digital media devices such as smartphones, laptops, tablets, camcorder, audio players, and digital cameras.

Most SD cards have a lifespan of 5 years or more. Frequently erasing data from an SD card can degrade the life of the card.
